Creeking Noise

[930LDR]

I stirpped out the interior on my 930 yesterday, seats, rollbar, carpets etc in preparation for doing a lightweight carpet kit.

After pulling the sound pad in the rear I boled in the drivers seat so that I could take it for a spin to see just how much louder it is.

Other than a couple of holes that were drilled through the firewall to run some wiring which were adding to the sound (and possibly carbon monoxide) It was louder but nothing that I won't be able to live with.

What I did notice though was some creeking noises as I went over speed bumps. Essentially when the front wasn't level with the rear.

Maybe its the lack of sound deadening, maybe the 2 degree Chicago weather, but I switched to coilovers last year and am concerned that maybe there is too much stretton the car. Or maybe there is something loose or broken somewhere.

Any suggestions or thoughts?

Thanks guys

I just did the whole carpetremoval/replacement deal and the only thing I noticed was the whine from my gearbox became MUCH louder.

Sounds like you just removed the last bit of structural integrity from your car.
Put the carpet back in.

Oh my, this sounds serious... you haven't already thrown it away have you?

[Craig 930 RS]

I hope he hasn't.

Otherwise the "creeking" may tun into a torrent - a "river", if you will - of trouble.

Glad we could help.

P.S. Sounds like torsions

Torsions are removed via the coilover conversion... could it be torsion tubes?

If you've removed the torsions, I'll offer that it's the shock mounts getting ready to self-distruct. I really doubt that they were designed to support the weight that you're putting on them. I'm sure there are many folks here who can better discuss the differences between the 80's cars shock mounts and the 90's cars with factory C/O, but in my racing experience we beefed up the shock/strut mounts significantly on coil over conversions. This was for Mustangs though - maybe the P-cars are already strong enough, but I wouldn't bet my paycheck on that.....

My money lies on the a-arm/banana arm bushings.

What rate springs are you running on the C/O's ? Without TB's ?

If you are not using 935 spring plates then it might be the original spring plate bushings.
